Specification of Letters Patent. t t t 19241 Application filed January 2, 1920. Serial No. 348,981.

means of various types of power plants in which oil is used as the fuel, and has for its object to provide for the automatic control of the flow of oil to the burner according to the speed of an engine or engines operated b steam pressure, the steam being derived rom the combustion of the fuel oil and for operating in conjunction with the usual manually controlledfiring valve of the engine so that an additional amount of oil can be supplied and controlled automatically according to the speed of-the engine.

A further object of the invention is to prevent the usual undesirable effect of allowing cold air to be drawn in through the fire box and flues of an engine or locomotive when in operation due to the frequent delay in readjusting the usual manual firing valve,

, and has further for its object to provide an economy in the consumption of oil and to materially reduce the expensive upkeep and,

repair of the boiler of the engine. The invention consists of the construction and details and the combination an embodiment of which is illustrated in the accompanying drawings and described and claimed herein.

A further object of the invention is to; provide in the combination also for the automatic control of a vaporizing fluid as steam for atomizing the oil in the burner.

Figure 1 is a side elevation of the improved automatic fuel saving and'controlling valve.

Fig. 2 is a plan view of the top end of the same.

Fig. 3 is a central, longitudinal section through the improved valve, taken on line 3-3 of Fig. 1'.

' Fig. 4 is a diagrammatic plan View of the combination of the automatic system with a steam power plant, taken on line 4-4= Fig.5.

Fig. 5 is a side elevation in diagrammatic being in section.

The present valve-is designed to be used of the plant parts of the cab for the automatic control of liquid fuel as in locomotives or other steam generating power sides steam pipes 5--6 to the former of.

which may be connected a supply pipe as 7 that may be connected to any chamber or medium as for instance to the main steam line L, Fig. 5, between the engineers throttle valve T and the cylinder C- of the engine, or may be connected to an exhaust chamber or pipe of the engine so that with the variation of pressure according to the position of the throttle valve T there will be a variation'efpressure in ,the steam chamber 3.

In this chamber there is mounted a piston 8 having a piston rod 9 passing through a gland 10 and having a collar 11 supported asby a pin 12 the collar supporting the upthe piston rod 9 and bearing on a transverse tie or bridge 14 connecting parallel side members 15 forming a part of. the general body 2.

The piston rod 9 passes freely through bridge or tie 14 and through a gland 16 and is provided with a suitable valve port closure or disk 17 operating in a passage way or chamber 18, one side of the valve disk 17 being designed to seat against the lower end of an outlet passage way 19 to which may be connected a discharge tube or pipe 20. The valve chamber 18 is shown as having an opening at one side to which is conand on the same there is adjustable a set of lock or clamp nuts 25 by means of which the degree of opening of the valve 17 may be precisely determined.

It will be seen from the above that as determined by the degree of pressure led into the steam chamber 3 the degree of opening or closing of the valve 17 is automatically the valve 1 rod or stem 9 is shown as threaded at 24,

ill

justment in addition to the adjustable set nuts which determines the degree of opening of the valve 17.

For the purpose of conveying away any condensate from the steam chamber 3 the latter may be provided at its bottom with a drain 3'. I

Preferably the steam passing into the chamber 3 above the piston 8 is, led out of the pipe 6 that is provided with a valve 6, Fig. 5, and is directed downwardly through the connection to the rear end of the burner B so that the oil. is atomized by steam passing through the steam chamber of the device. llhe valve 6' may be closed and live steam led to the steam pipe 30 by a live steam pipe 31 connected to the steam drum D of the boiler A, and this steam may be controlled by the valve 31 in the line 31.

A'check valve 31 is arrangedin the line 31 to prevent back pressure from the connection 6 and another check valve 6* is introduced below the outlet 6 to prevent back pressure from the live steam slde.

As shown in Fig. t the oil feed pipe 21 is extended from a main supply line 21 that has a branch 21*, with the valve V, leading to the burner B so that when the manual valve V is closed oil may be conducted from the feed line 21 to the connection 21 and this flow may be controlled by a valve 21 suitably located in the supply line at a point beyond the branch having the manual valve V. 1

Various changes may be made without departing from the spirit of my invention as claimed.

ll claim:

1. An automatic fuel regulator compris ing a body frame having at one end, a steam head and at the other an oil chamber with means for connecting to a source of supply; a piston in the steam head having a stem with a valve for controlling flow of oil from intense ing a body frame having at one end, a steam head and at the other an oil chamber with means for connecting to a source of supply; a pistonin the steam head having a stem .With a valve for-controlling flow of oil from the oil chamber; and means for normally moving the valve toward its: seat; the said means including a spring coiled about the stem and disposed between the steam head and oil chamber. 3. The combination in a steam power plant, of a furnace with an oil burner; an automatic regulator operative by steam pressure that is initially controlled by the throttle valve of the plant; an oil supply pipe having a valved connection directly to the burner and havinga valved branch connected to the regulator and through which the flow of'oil is controlled-by the operation of the regulator; and a steam connection between the regulatorand the burner whereby steam utilized in the operation of the regulatoris supplied to the burner for the atomization of the oil.

at, An automatic fuel regulator, comprising a body frame having a fluid pressure chamber at one end and an oil chamber at its opposite end, a piston in the fluid pressure chamber having a stem extending mto the oil chamber, an oil control valve on said chamber at one end and an oil chamber at its opposite end, a piston in the fluid pressure chamber and an oil control valveheld normally, seated in the oil chamber, said piston and the oil valve being operatively connected by a common stem, fluid pressure inlet and outlet ports disposed on one side of the piston, oil inlet and outlet ports disposed on opposing sides of the oil valve seat, and resilient means disposed on the stem intermediate the fluid pressure and oil chambers to hold the oil valve normally seated, and adjustable means on the stem to limit the opening movement of the oil a valve.

In testimony whereof l have signed my name to this specification.
